(HealthDay)—High penicillin G prescribing may lead to an altered level of resistance in the commensal viridans group streptococci (VGS) population, which may be important in subsequent horizontal gene transfer ...

We've heard a lot lately about superbugs – bacteria that are resistant to current antibiotics. But as the threat of superbugs continues to rise, the number of new treatments available has flatlined. This ...

Researchers are reporting another disappointment for efforts to cure infection with the AIDS virus. Six patients given blood-cell transplants similar to one that cured a man known as "the Berlin patient" have ...

New Swedish research shows that plasmids containing genes that confer resistance to antibiotics can be enriched by very low concentrations of antibiotics and heavy metals. These results strengthen the suspicion that the antibiotic ...

Imagine going to the hospital with one disease and coming home with something much worse, or not coming home at all. With the emergence and spread of antibiotic-resistance pathogens, healthcare-associated ...

(Medical Xpress)—High school biology taught us that we inherit certain traits from our parents that are pre-determined. But what if you could change how these genes play out by taking certain drugs or better yet, just changing ...

(Medical Xpress)—In two new studies, scientists use genome sequencing of worldwide samples to show that bacteria can take very different routes to becoming a successful disease. Researchers can use these ...

A team of clinician researchers has discovered a highly virulent, multidrug resistant form of the pathogen, Pseudomonas aeruginosa, in patient samples in Ohio. Their investigation suggests that the particular genetic elemen ...

(HealthDay)—Researchers have identified genes that may help predict whether a patient with estrogen receptor (ER)-positive breast cancer is likely to benefit from tamoxifen therapy, according to a study ...

Researchers from BGI, working within the Metagenomics of the Human Intestinal Tract (MetaHIT) project, and in collaboration with other institutions around the world , have established the highest quality integrated gene set ...

A fungus living in the soils of Nova Scotia could offer new hope in the pressing battle against drug-resistant germs that kill tens of thousands of people every year, including one considered a serious global ...

Drug-resistant bacteria annually sicken 2 million Americans and kill at least 23,000. A driving force behind this growing public health threat is the ability of bacteria to share genes that provide antibiotic ...

Continually under attack by noxious substances in their environments, bacteria have developed many clever mechanisms to survive. When confronted with an antibiotic, they can destroy it with enzymes, rendering ...
